A cold front advancing through southeastern Brazil is the main driver behind the tight clustering of trader probabilities around 20–21°C for São Paulo’s June 12 maximum, with INMET guidance highlighting cooling and rain expected through June 13. Typical June climatology features daytime highs near 22°C, but the frontal passage introduces downward pressure via increased cloud cover, northeasterly flow, and potential showers that limit daytime heating. Ensemble forecasts show modest spread in peak values depending on exact frontal timing and boundary-layer moisture, producing the observed market distribution where 20°C and 21°C together exceed 65% implied probability while warmer or cooler outliers remain under 10%. Updated model runs and INMET briefings over the next 24 hours will likely narrow the range.
